Expression and preliminary evaluation of the recombinant antigens RV2031c and 38kDa and the recombinant chimeric antigen CFP10-ESAT6 in the serological diagnosis of tuberculosis
Objective To evaluate the effectiveness of the recombinant antigens Rv2031 cand 38kDa and the recombinant chimeric antigen CFP10-ESAT6 of Mycobacterium tuberculosis and a mixture of those antigens to serologically diagnose tuberculosis. Methods PCR was used to amplify the three antigens from the genomic DNA of the H37 Rv strain of M.tuberculosis.The product was cloned into pET-30 aand pET32avectors and transformed into E.coli BL21(DE3)strain for expression.Proteins were purified using Ni-NTA His-binding res...
